TYPEWRITING MACHINE.

Application filed August 5, 1921. Serial No. 489,880.

To all 20720171716 may concern:

Be it known that I, BURNHAM C. Srrox- NEY, a citizen of the UnitedStates, residing in Elizabeth, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in TypewritingMachines, of which the following is a specification. I

This invention relates to'mechanism of the continuous billing orso-called fan-fold type, such as shown in the patent to VVernery &Smith, No. 1,132,055, granted March 16, 1915, and is herein disclosed asapplied to a bookkeeping machine of the Underwood- Hanson type;

Heretofore, it has been impracticable to use a carbon-carrier and otherfeatures of the continuous billing or fan-fold type of mechanism on thebookkeeping machine .of the type referred to, since thedenominationselecting mechanism at the rear of the lastmentioned machinenecessitates the positioning of the extension or track for thecarhon-carrier at such a height above the normal position of the platenthat the latter cannot be lifted suiiiciently by the usual mechanism toenable sufficient straightening of the web to permit the withdrawal bythe carbon-carrier of'the' carbon-sheets attached thereto. Furtherdifiiculties also arose due to the fact that the forward end of thetrack would interfere with the adjustment of the denomination-selectorat different positions along the carriage and also with the positioningof the tabulator-stops It will be evident that .the diflioulty found inadjusting the tabulator stops on the bookkeeping machine equipped withfan-fold mechanism also exists in the usual typewriting machine of thecontinuous billing or fan-fold type.

According to one form of the invention, the excessive bending of thewebs over the guide at the front end of the track located above thedenomination-selecting mechanism is substantially avoided, by supportingthe carriage extension or track in an inclined position. It willbe seenthat by giving the track a suitable inclination, the bend in the Websover the forward end of the track may be sufliciently diminished or eveneliminated in straightening the webs when the platen is in raisedposition.

In order to render the back of the bookkeeping machine accessible foradjusting the 1 and hold it in raised selector-dogs and tabulator-stops,the fanfold extension or track is supported on a rear rail so that itmay be swung about the same to raise the forward end of the exten sionfrom engagement with the rear of the carriage on which it normallyrests. To limit the upward movement of the extension position, whendesired, provision may be made of suitable means, such as atogglelevice, which may be utilized to hold the extension in raisedposition, the to 'gle being collapsible to enable the return or theextension to its normal position.

Due to the normal inclination of the carhon-carrier and the variation insuch inclination in swinging the trackabout the rear rail, the carriertends to slide along the track. To prevent such accidental movement ofthe carbon-carrier, provision may be made of suitable braking meanswhich, while permitting manual movement of the carrier, will preventaccidental movement.

Usually the rail on which the rear of the carbon-carrier track travelsis supported by a frame connected to the back of the typewriter frameand resting directly on the same surface as the typewriter. Inasmuch asthe typewriter of the bookkeeping machine rests upon the computer casingand the latter is usually mounted on a stand, it is impracticable tosupport the rear rail in the usual manner, since the top of the computercasing is only' of sufficient size to receive the frame of thetypewriter proper. It has been found advantageous, therefore, to supportthe rear rail for the carbon-carrier extension upon brackets secured tothe rear of the typewriter frame.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a diagrammatic side view showing the carbon-carrierpositioned at the rear and the platen in position to receive typingthereon.

Figure 2 is a plan view of the structure shown in Figure 1.

Figure 3 is a view similiar to Figure 1 but with'the platen raised andthe web straightened, the track for the carbon-carrier being shown inraised position in dotand-dash lines.

Upon depression of the keys (not shown) of a typewriter forming part ofa bookltee ing machine of the Underwood-Hanson type,

j a cylindrical platen 13, mounted on an axle 1'4journaled in a carriage15, which is supported for sliding movement transversely of thetypewriter by means including a rear rail 16 fixed on the typewriterframe 17. Each type-bar in its effective movement actuates the usualescapement mechanism (not shown) and effects a letter-feeding movementof the carriage.

As is usualin' bookkeeping machines of the type referred to the frame 17of the typewriter is set on the casing 18 of the computing mechanism,and provision is made of means whereby the letter-feeding movement'ofthe carriage will effect denomination-selecting for the computingmechanism. To this end, provision is made of brackets 19 extendingrcarwardly from the type writer carriage and of rods 20 and 21 car-'ried thereby. Rotatably and slidably mounted on the rod 20 is adenominationselector 22, which may be held in proper letter-spacepositions therealong by means of a tooth 23 engaging notches in the rod21, the selector 22 normally lying in de pressed or ineffectiveposition. Obviously, a lurality of selectors may be used.

pon a letter-feeding movement of the carriage into a computing zonedetermined by one of the selectors, a frusto-conical roller 24 on therear end of the selector 22 will ride up on the conical end of a roller25, having a cylindrical portion of substantially, the length. of thecomputing zone, and cause a tappet 26 on the selector to engage seriatimthe forward ends of jacks 27 of a certain set, to advance seriatim theusual pin'barsby connections (not shown). Provision is made of the usualjack-housing 28 and the usual housing 29 for thethrust-rods (not'shown),by which the movements of the jacks 2'7 are transmitted'to the computingmechanism, the housing 2-9 being connected to the jack-housing 28 at itsforward end by any suitable means, such as ears 30, and the jacks andjack-housing being supported on the typewriter frame by any suitablemeans, such as a bar 29? and brackets 29 There maybe several sets ofjacks, and actuation of a set ofjacks by one selector 22 and not'byothers may be obtained by arranging the different sets with the forwardends of the jacks extending to different positions toward the front ofthe machine, and by arranging the tappets 26 on the different selectors22 in accordance with thesets of jacks to be actuated thereby. Thebrackets 19 may also be utilized to support a toothed bar 31, on whichmay be po sitioned, at letter-space intervals, tabulatorstops 32 inposition to be engaged by counter-stops 33, when the latter are liftedby means (not shown). The computing mechanism and thedenomination-selecting mechanism, forming part thereof, may be, ingeneral, similar to that disclosed in the patent to Richard M. Becker,No. 1,296,355, granted March 4, 1919. Y

Inasmuch as the present invention contemplates the use in a bookkeepingmachine of the features of a continuous billing or so-called fan-foldmachine, the axle 14 of the platen is journaled in ends 34 of aplaten-lifting frame, said ends 34 being pivoted at the front of theplaten on a rod 35, and being supported in normal'position by arms 36,forming part thereof and resting on a rod 37, supported on the carriagebeneath the upper end of the rear paper table 38. To insure the properretention of the ends 34 in their normal positions,

provlsion is made of means, including an arm 39, mounted on the rod 37and having on the frontside thereof a hook 40, to engage over a pin 41on the adjacent end 34 of the platenlifting frame. The arm 39 may belimited in its forward movement by a lug 42 extending below the rod 37so to engage a fixed part of the carriage when the arm 39 is in itsforward position. Helease of the platen-lifting frame may be effected byswinging the arm 39 to the rear bymeans of a finger-piece43 at its upperend.

Due to the projection of the jack-housing 28 above the platen, it is notfeasible to use a horizontal carbon-carrier-track frame, as is usuallythe case. in continuous billing or fan-fold machines, since the webs orplies 44 would necessarily be bent downwardly over the front end ofsaid. frame or table and upwardly around the platen, even when theplaten is in its raised position, and the friction between thewebs andthe carbon sheets would be so great that the latter could not beretracted. According to this invention, the carbon-carrier-track orrearward extension 45 of the carriage 15 is mounted, in an inclinedposition, so that the webs 44, in passing over the track, will beinclined forwardly and downwardly, and pass to the elevated platenwithout bending down over the front end of the .carbon carriertrackframeor table. It. will be evident that the carbon-sheets may bewithdrawn even if the webs cannot beentirely straightened under theplaten, the only requisite being that the bends in the webs andinterleaved carbons must be reduced sufiiciently to permit slipping ofthe carbon-sheetsbetween the webs. The plane of the carbon-carr ertrackframe or table may be substantially tangential to the bottom ofthedisplaced platen.

The rearward extension 4 Which maybe referred to in general asthecarbon-carriertrack, comprises front and rear. rods 46and 47,respectively, connected by a plurality of.

stepped blocks 53 on which are supported blades 54, to which thecarbon-sheets 55 are attached at their rear ends. For convenience inshifting the carbon-carrier on the rails 49, provision is made of aforwardlyextending arm 56 having at its end a fingerpiece 57, which mayeasily be grasped by the operator and used for shifting thecarboncarrier 53. i For reasons which will appear more clearlyhereinafter, provision is made of leaf-springs 58 attached to the plate52 near its forward edge and pressing against the rails 49, so as toresist accidental movement of the carbon-carrier along the track,

To limit the movement of the carbon-carrier along the rails 49,provision may be made of a stop or stops58.

At its rear, the extension 45 is supported by arms 59 depending from theoutside rods 48, and each of the arms is provided with a roll 60 havinga concave. groove therearound to fit on a rail 61 which serves as asupport therefor, engagement of the rail 61 by the rod being insured byan offset portion of each of the arms 59, extending beneath the rail 61'in such a manner as to prevent the lifting of the rolls 60 therefrom.Inasmuch as the typewriter frame 17 is supported by the computer casing18, it is not feasible to support the rail 61 in the manner usual incontinuous billing or fan-fold machines, and it has been foundconvenient to use brackets 62 attached to the typewriter frame at itsback and near the sides thereof by suitable means, such as screws 63.

To support the extension 45 at its front end, suitable brackets 64 areattached to a bar 65 forming part of the carriage, and

these brackets are provided at their upper ends, above thejack-housings, with recesses 66 to receive the reduced end or portions67 of the front rod 46 of extension 45. It will be seen that theshoulders formed at the ends of the reduced portions 67 engage the innerfaces of the brackets, thereby preventing relative movement, transverseto the machine, between. the extension and the typewriter-carriage. Oneadvantage of this arrangement resides in the fact that it permits thefront end of the extension 45 to be swung upwardly, thereby makingaccessible the denominationselecting mechanism normally lyingtherebeneath. so as to render it convenient to adjust the latter, whennecessary. I

To limit the upward movement of the front end of the extension 45 and todetain it in raised position when desired, a link 68 is pivoted at oneend to the left-hand end of the rod 46 and also by means of a pivot 68to one end of a link 69 mounted at its other end on a pivot or screw 7 0carried by the lefthand bracket 64. Suitable provision may be made forlost motion at the pivot 68 to avoid any interference with the upwardswinging of the track 45. Upon lifting the forward end of the extension45, the link 68, and, consequently, the link 69, will be shifted fromthe position shown in Figure 1 to theposition shown in FigureB, the link69 then resting on a stop-pin 7O carried by the left-hand bracket 64. Inthe normal position of the link 69, a lug 69 forming a prolongationthereof beyond the pivot 76 engages the pin 70 if desired, provision maybe made of a hook 71, which, when swung into position, will engage theshaft or rod 46 and prevent accidental displacement of the latter. Itwillbe obvious that the leaf-springs 58 tend to maintain thecarbon-carrier 53 in any position to which it has been moved during themovement of the extension 45 to and from the raised position shown indot-and-dash lines, Figure 3.

When the machine is to be used, the platen-lifting frame is released bygrasping the finger-piece 43 and swinging the arm 39 rearwardly. Thelifting frame is then swung about the rod 35 until it assumes theposition shown in Figure 3 and the webs 44, which have been passed overthe rear rod 47, between the carbon-sheets 55 and over the front rod 46,are led beneath the platen and over a knife 72. The platen is then swungto its normal position to co-operate with feed-rolls 73 and the machineis ready for use. After typing a line on the webs, they may be advancedby operating the usual linespace mechanism, not shown. Such opera tioncauses actuation of a gear 74, which, through a broad gear 75, actuatesa gear 76 mounted on the end of the platen-axle. The line-spacingaction, in printing on a-set of forms such as are usually carried by thewebs in use in the continuous billing machine, will advance the forwardends of the webs alonga front paper-table 77, which forms part of theplaten-lifting frame, and when the typing of a form has been complet ed,the lifting frame will again be swung to the Figure 3 position, and theleading ends of the webs grasped by the operator and drawn forward intocontact with a gage 7 8 secured by a screw 79 at any desired positionalong a bar 80 forming an extension of the front paper-table 77. Theoperator, while holding the leading edges of thewebs in gaged position,may grasp the fingerpiece 57 with the other hand, and press the same'rearwardly to shift the carbon-sheets 55 into position between unusedportions of the webs. After restoring the platen to its mounted positionand severing the used portions of the webs by drawing the same acrossthe knife 72, typing may be begun on another set of forms on the webs,and the operation described. may be repeated as many times as required.

Inasmuch as the fan-fold mechanism. whose so has just been described, ismounted, as, herein disclosed, on a boohl-ceepin machine of theUnderwood Hanson type, typing of digits may be accompanicdby computationin. either one or both of the totalizers (not shown) associated with thetwo sets of jacks. The selectors 22 maybe adjusted at suitableletter-space positions along the rod 20 by swinging them upwardly towithdraw their teeth 2-3 from the notches in the rod 21 and sliding themalong the-rod 20 to the desired positions. hen such settings of theselectors 22 and of the tabulatoustops 32 are to be effected, thecarbon--carrier-track 4L5 is moved out of the way by swinging it to theraised position shown in dot-and-dash lines in Figure lVhen such settins have been made properly the typir 4 t and the correspondingcomputa nma be effected concomitantly during the passage of the carriage 15through any computin none determined by a selector Variations may beresorted to within the scope of the invention, and portions of theimlnovements may be used nt others.

A machine for typing upon superposed plies of web, comprising atypewriter frame, a platen, a platen-carriage mounted to travel alongsaid frame, said carriage comprising a frame upon which the platen maybe displaced upwardly for straightening out the web to permit thecarbons to be shifted between the plies of web, a carboncarrier, acarbon-carrier supporting and guiding table connected to the carriage totravel therewith, the forward end of said table being at the rear of theplaten and at a substantially higher elevation than the platen, to clearelevated stationary parts at the rear of the typewriting machine whichco-operate with the carriage, as set forth, the .web running forwardlyover the carbon-carrier, and bending down around the front of said tableand under the platen to feed up in front thereof, said platen when inits elevated position being below the front of said table, and thelatter being in clined rearwardly and upwardly from its front end, sothat the plane of the inclined table is about tangential to the bottomsurface of the platen when in elevatedposition, to permit the web to runoff from the table to the bottom of the platen, without being bent downaround the front edge of said table, thereby to permit the web to bestraightened out sufficiently to permit the shifting of thecarbon-sheets between the plies of web, and means to overcome thetendency of the carbon-carrier to slide down along the inclined table. a

27. In a front-strike typewriting machine, a carriage, and a revolubleplaten displaceable upwardly in the carriage sufiiciently to straightenout the work-sheets to permit carbons to be shifted back along the web,said machine comprising adding mechanism having parts to co-operate withthe carriage, said co-operating parts mounted at the rear of thecarriage and above the level of the platen when the latter is in typingposition, a carbon-carrier, and a track therefor connected to andextending backwardly from the typewriter carriage, said track beingabove said adding-machine mechanism, and extending in a directionsubstantially tangential to the bottom of the platen when the latter isdisplaced upwardly for so straightening out the work-sheets.
